In recent years, 4D product production based on UAV low-altitude remote sensing system, small-scale surface monitoring, emergency data collection technology, rapid production technology of large-scale topographic maps and other surveying and mapping-related technologies have been maturing, providing corresponding technical services for rapid acquisition and application of regional large-scale basic geographic data and rapid acquisition of surface data for emergency processing. Low-altitude remote sensing system based on UAV has also been applied in mine surveying. In order to provide some reference on the application of remote sensing drone technology for surveying and engineering mapping, the present paper briefly presents the development of remote sensing drone technology and discusses the impact of the application of remote sensing drone technology for surveying and engineering mapping. With a particular project for example, this paper will analyse the application of remote sensing technology of unmanned aerial vehicles (UAVs) in survey and investigation engineering mapping and its impact. The results show that the application of unmanned aerial vehicle remote sensing technology can improve the accuracy and efficiency of engineering surveying and mapping. Therefore, UAV remote sensing technology should be reasonably applied according to the actual situation in surveying and mapping.
